KE Arms KE-9 Complete Lower Billet 9mm Black Finish from Riflecrafters LLC near Meridian, Boise, ID

The KE-9 Billet lower receiver is precision machined in-house from hi-grade billet master plate to Milspec standards making it compatible with most milspec 9mm uppers. Features a broached mag well and Milspec 8625 type III, class 2 hard anodized. The KE-9 accepts Glock OEM and after market Glock style magazines.

This lower features an Ambidextrous magazine catch assembly making it optimal for Left Handed shooters or shooters that need complete ambidextrous handling of their firearm.

This lower comes assembled with either our DMR or SLT-1 Trigger and Ambidextrous selector. The magazine catch is machined from billet and hard anodized. The rest of the parts are our standard mil-spec components all made in the USA. Our 5.5oz heavy 9mm buffer is installed. Includes X-Tech Grip and M4 Stock. Mount the upper of your choice with bolt carrier group that clears through Glock feed ramps, and this unit is ready to go!

The KE-9 DOES NOT have Last Round Bolt Hold Open (LRBHO) unless you use an upper with a linkage system built in to accommodate it. The AR15 magazine catch can be used to manually lock the bolt back, but Glock magazine followers DO NOT interface with it. To have LRBHO you must use an upper with a linkage system that interfaces with the Glock magazine follower and standard bolt catch. Some manufacturers of 9mm uppers produce uppers with this feature.

These lowers are for use with traditional blow-back system uppers only. Will not work with CMMG Radially Delayed Blowback uppers. Seriously if you want a reliable softer shooting 9mm AR, use a heavier 7oz-10oz buffer and Sprinco Orange Spring.
